Andrzej Sapkowski, known for writing the series of novels that would be adapted into the video game franchise of The Witcher, is threatening developer CD Projekt Red with legal action. Sapowski demands about $16.1 million in royalty fees for the success of The Witcher intellectual property. The demand stems from a Polish law that states if a creator isn’t given a proportionate amount of money for their creation, then they’re due to claim more in a settlement. CD Projekt Red opposes Sapkowski’s demands, claiming that they paid a flat fee when originally securing the rights to make a series of video games. Originally, the company approached the author with plans to offer a percentage of profits from sales, but Sapkowski believed that the games would be unsuccessful, so he took an initial one time payment instead. CD Projekt Red has until October 9th to come to a conclusion on the matter, or else they’ll face legal troubles.
